Pitcher suddenly interrupted his work introducing him a new stenographer. Maxwell was very surprised. “How could I give such an order? Miss Lesley has been working excellently for the whole year. We have no vacancies. The new stenographer left the office indignantly.
There was relaxation in work shortly before breakfast time. Maxwell was standing near his table with hands full of letters and telegrams, his hair were hanging over the forehead. The window was opened and spring was looking through. He felt a smell of lilac. This smell reminded him about something. The world of business disappeared instantly.
She was in the next room. “I swear on my honour, I’ll do it. I’ll ask her at once,” –Maxwell said and ran towards the stenographer’s room.
“Miss Lesley, - he said hurriedly, - be my wife, I love you, I’ve wanted long to tell you about it and now I spared a minute during short relaxation in the office. Answer quickly, I’m wanted on the phone.
The stenographer behaved very unusual. At first she was amazed, tears ran out of her eyes, and next she smiled and put her arms round his neck. “I got it – she said gently – work makes you forget everything. Did you really forget that we got married yesterday in the small church round the corner?”
